Beschreibung:
In this study, by utilizing all three primary components (cellulose, hemicellulose, and lignin) of lignocellulosic biomass, we develop an integrated strategy for coproduction of hydrocarbon fuel (5-nonanone) and bio-chemicals (furfural and high purity lignin). After biomass fractionation: (1) using cellulose derived -valerolactone (GVL), 5-nonanone is produced, which can potentially serve as platform molecule to produce liquid hydrocarbon fuels for the transportation sector, (2) using hemicellulose, a valuable platform chemical, furfural is produced, (3) lignin is converted into high purity lignin, which can be used to produce carbon foams or battery anodes. To effectively recover the solvents, for reuse in conversion processes, separation subsystems are designed which eventually lead to improve the economic feasibility of integrated process. We introduce a heat pump and perform heat integration, for reduction in utility requirements. Eventually, to highlight major cost and technological drivers of the integrated process, we perform a wide range of techno-economic analysis
